SQ on a bank statement means the payment was processed through Square, the card-processing platform owned by Block, Inc. The charge appears as “SQ *” followed by a shortened version of the merchant’s business name, and it points to a specific seller (usually a small business) that accepted your card through a Square reader, invoice, or online checkout. If the truncated name doesn’t tell you who it was, Square runs a free receipt lookup that will.
How the SQ Descriptor Is Formatted
Square uses a consistent pattern: SQ * followed by the business name as the seller entered it in their Square dashboard.1Square. Square Statement Descriptions A pharmacy called “My Pharmacy” with store number 02943 shows up as SQ *MYPHARMACY*#02943. Square gets only 20 characters after the SQ * prefix, so longer names get cut off, and any store number tacked on the end may be truncated further or hidden entirely inside a mobile banking app.2Square Developer. How Do I Change the Business Name That Appears on Card Statement Receipt
That truncation is why so many SQ charges look unfamiliar. You’d recognize “Joe’s Coffee” but not “SQ *JOESCOFF” with the rest chopped off. The name is whatever the merchant typed when setting up Square, which isn’t always what’s on the storefront sign or website.
Related Prefixes You Might Confuse With SQ
Block, Inc. (renamed from Square, Inc. in December 2021) also owns Cash App, so several SQ-adjacent descriptors travel through the same corporate plumbing.3U.S. Securities and Exchange Commission. Form 8-K Current Report Block, Inc. It helps to know which one you’re looking at:
- SQ * is a standard in-person or online payment to a merchant using Square’s processing.
- CASH APP* is a peer-to-peer transfer through Cash App, often followed by the recipient’s name or $cashtag.
- SQC* is tied to Square Capital, LLC, Block’s lending arm, and usually relates to Cash App’s buy-now-pay-later product rather than a routine purchase.
- CK* or CA* are purchases made using a Cash App Card at a retailer, sometimes followed by the merchant name.
If you see SQC* and don’t remember signing up for financing, treat it as something to investigate right away. Regular coffee-shop purchases don’t produce that prefix.
How to Identify the Merchant Behind an SQ Charge
Read the Full Descriptor First
Start with everything after “SQ *” on your statement. Mobile banking apps often hide part of the descriptor until you tap into the transaction. The full entry usually contains enough of the business name to jog your memory, especially checked against your calendar or any receipts you have for that date.
Run It Through Square’s Receipt Lookup
If the shortened name still means nothing, Square offers a free receipt lookup at squareup.com/receipts. You need three pieces of information: the date of the charge, the exact dollar amount, and the last four digits of the card used.1Square. Square Statement Descriptions The tool returns the merchant’s business name and contact information. This is the fastest way to resolve a mystery charge before escalating anywhere.
Search Your Email for a Digital Receipt
If you’ve ever entered your email or phone number at a Square checkout, that contact information gets linked to your card. Future purchases with the same card at any Square merchant can send you an email receipt automatically, without you doing anything at the register.4Square Support Center. Manage Automatic Receipts for Square Customers Search your inbox for “Square” or “SQ” around the date of the charge. Square doesn’t share your contact details with the merchant, so this can surface receipts from businesses you’ve never given your email to directly.
What to Do If You Don’t Recognize the Charge
Before filing a dispute, rule out the ordinary explanations. Check with anyone else on the account, look for a subscription renewal you may have forgotten, and confirm the amount matches what you’d have paid after a tip. A large share of “fraudulent” SQ charges turn out to be a partner’s coffee run or an annual renewal.
If you’ve ruled all that out, your next step depends on the card. Federal protections work differently for debit and credit.
Debit Card Charges
Debit card transactions are covered by the Electronic Fund Transfer Act. You have 60 days from the date your bank sends the statement showing the unauthorized charge to report the error. Reports can be oral, but the bank can require written confirmation within 10 days.5Office of the Law Revision Counsel. United States Code Title 15 – 1693f Once you’ve reported, the bank must investigate and resolve the matter within 10 business days, or extend to 45 days if it provisionally credits your account and gives you full use of the funds while it investigates.6Consumer Financial Protection Bureau. Section 1005.11 Procedures for Resolving Errors
For point-of-sale debit transactions specifically, the investigation window stretches to 90 days. The same extension applies to international transactions and charges on accounts less than 30 days old.6Consumer Financial Protection Bureau. Section 1005.11 Procedures for Resolving Errors Most Square charges are point-of-sale debit transactions, so the 90-day timeline is the one you’ll usually see.
Credit Card Charges
Credit card disputes fall under the Truth in Lending Act and Regulation Z. You still have 60 days from the statement date to send a written billing error notice. While the investigation runs, you don’t have to pay the disputed amount, and the issuer can’t report it as delinquent or close your account for exercising your dispute rights.7eCFR. 12 CFR 1026.13 – Billing Error Resolution
How Fast You Report Controls What You Owe
On the debit side, the timing of your report sets your maximum liability:
- Reported within 2 business days: liability capped at $50 or the amount of the unauthorized transfers made before you called, whichever is less.8eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- Reported after 2 business days but within 60 days of the statement: liability rises to as much as $500.8eCFR. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
- Not reported within 60 days of the statement: you can be liable for the full amount of any unauthorized transfers that occur after that window closes.9Office of the Law Revision Counsel. United States Code Title 15 – 1693g
Credit cards carry lower risk. Federal law caps liability for unauthorized credit card charges at $50, and most major issuers waive even that under zero-liability policies.
If you can’t identify an SQ charge, don’t let it sit. Run the receipt lookup first, and if nothing matches, call your bank within two business days to keep your liability at its floor.
